Patenten Nev. a, rare.

To all 'whom it may con/ccm Be it known that I, HENRY FREDERICK KUHLMANN, a citizen of the United States, residing at'lndianapolis, in the county of Marion and State of Indiana, have invented certain new and useful improvements in Washing-Machines, of which the following is a specification.

My invention relates to a new and useful improvement in a washing machine. The object of this invention is to provide a device in which the clothes are moved in and out and back and forth in a serpentine path through the water in the receptacle by an agitator in such a manner that they are pounded or bufeted by teeth carried on the agitator to loosen the dirt, and the water passes through the fabric to wash out the dirt. which has been loosened.

l'Vith this` and other objects in view my invention consists of novel features of con-v struction and operation which will he clearly understood from the following specification and the accompanying drawings, in which Figure l, is a cross section .through the washing machine, Fig. 2, is a bottom plan view o the agitator and Fig. 3, is a detail view of the agitator and operating mechanism.

A represents the ordinary tub provided with a cover B, hinged as shown at C to a bar D secured to the tub. The crank l is mounted upon a shaft 2, which extends through the cover and has connected thereto an agitator 4. The agitator consists of bars ecccntrically mounted on the shaft, each bar forming long and short arms 6 and 7. Each arm is provided with a V shaped tooth 8, the direction of bevel of the teeth alternating. The bevel surface of the teeth on the arm G projecting inwardly toward the axis of rotation and the bevel surface-of the teeth on the short arm 7 projecting out-` wardly toward the wall of the receptacle. The shaft 2 supporting the crank l, .is provided with a cross pin 9, which enters a groove 10 in the underside of the crank which keys the crank to the shaft. A nut 1l may be used for further securing the crank upon the shaft.

Thefoperation of the machine is as follows: An. oscillatory motion is given the crank l whereby it is transmitted to the agitator. Owing to the fact that the direction of the bevel of the teeth alternate, and

that the bevel surface of the teeth on the long arms project inwardly toward the axis of rotation, the -clothes being washed, will be drawn from the outenedge ofthe tub toward the center, and at the same time will be pushed forward, while the outwardly projecting teeth on the short arms having their beveled surfaces projecting outwardly toward the walls of the receptacle will draw the clothes, being washed, from the center toward the'outer edge and at the same time push them forward. In this way the clothes are buifeted in and out from one set of teeth to the other and in a serpentine path back and forth around the receptacle.

l't is evident that more or less slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact construction herein set forth, but

Having fully' described my invention, what I claim as new and desire to secure by Letters Patent is A washing machine comprising an agitator having arms, V-shaped teeth mounted on the arms, said teeth alternately arranged, and the V-shaped edges of the outer teeth projecting inwardly and the V-shaped edges of the inner teeth projecting outwardly, and means for operating the agitator whereb` the clothes will receive a back-and-forti movement, as well as an inwar'd and lo utward movement. i
